A famous scientific plotting package, features include 2D and 3D plotting, a huge number of output formats, interactive input or script-driven options, and a large set of scripted examples.

Mathpad is a command line utility. It will later have a GUI, but not at this time.

Matt's MathTools is a Java application designed as an aid in preparing printed math tests. It is easily embedded in other Java applications or it can be used alone as a single-user desktop app. It includes a scripting environment, numerous demonstration classes and several general utilities. A scripting tutorial is also available.

Average is a simple and fast command-line Perl utility for calculating basic statistics on a list of numbers (one number per line). It works as a traditional Unix filter and can be used as part of those greatly useful chains of piped commands. It calculates average (arithmetic mean), standard deviation, median, total sum, minimum and maximum values present, and shows the number of processed numbers.

It is often necessary to assign a series of discrete values to continuosly variable data sequenced by time, position, etc., thereby parsing the data into fewer and larger segments of variable width. The 'segment' utility takes an input data stream as a Hidden Markov Model and applies the Viterbi algorithm to find the most likely segmentation path through the data.

It is often necessary to smooth high frequency fluctuations out of data streams sequenced by time, position, etc. The 'smooth' utility applies such smoothing using the wavelet algorithm. This implementation of wavelet smoothing was optimized for use in a data stream. It was adapted from HMMSeg Wavelet.Java by Thomas E. Wilson, University of Michigan. HMMSeg Wavelet.Java was written by Andrew Hemmaplardh, University of Washington. http://noble.gs.washington.edu/proj/hmmseg/ Unsupervised segmentation of continuous genomic data, Bioinformatics 2007 23:1424-1426 See the above references for a more thorough description of the principles behind wavelet smoothing.

MooGraph is an utility to produce interactive dynamical graphs from statistical data. Deliberately inspired to GapMinder, it represents the evolution of multivariate data in time by means of coloured bubbles of variable sizes on an (x,y) plot.

VMatrixLib is a little, handy, Java matrix library which implements a set of utility functions (such as calculus of the determinant of a matrix, calculus of the rank, inverse matrix, and many others..) that anyone who have to use matrices needs.

A cross-platform, text-interpreting calculator written in the Java programming language. Runs on any computer with Java 6 or higher installed. Functions much like a Ti-84, but without the graphing utility.

The EconoMind is a utility that simulates the economy of a city, state, country, or planet at a specific level of technological development. It runs behind the scenes and provides supply, demand, and other information for games and other projects.

HicCalc is a scientific utility written in Java,that runs on all java supported operating systems. The current release contains the graphing part of the product. Please visit http://www.hicsys.com/hiccalc.htm to check out the online demo.

TaDaPro is a command-line utility to operate with numerical column tabulated data. It is intended for operations that are cumbersome to do by hand in a spreadsheet, and for transformations that have to be applied as a batch process on many files.

A C++ utility library featuring a javascript interpreter, regular expressions, automatic arrays, garbage collection, matrix handling, planar geometry (regions etc) and other useful features. Blends well with STL code.

BeastCalc is portable, cross-platform graphing calculator utility written in Java.

SVGMath is a command-line utility to convert MathML expressions to SVG, written entirely in Python.

A small utility for visualizing graphics of the wide math function list. Based on Glade/GTK+ toolkit so integrates into GNOME flawlessly. Uses mathGl library for drawing purposes, see http://mathgl.sourceforge.net/

Boolean Expression Solver is a command-line utility that generates a truth table for a given Boolean expression.

Math4J is a java library with an object-oriented design of some mathematical ideas: functions, primality, complex numbers, etc. It also consists of some utility methods and classes for mathematical constructions.

This project aims to deliver a high-quality number base converter utility in Java. It will support decimal, binary, hexadecimal, octal, and a user specified base and convert between numbers of any base from 2 through 36.

A collection of various Java utility interfaces and classes, concentrating on collections, data structures, algorithms, number theory, matrices, and other mathematical constructs.
